#!/usr/bin/env python3 """ Extension for InkScape 1.0 This extension parses the selection and will put all elements into one single group. If you have a cluster with lots of groups and elements you will clean up this way (one top level group, all elements below it). If you select a single element or a set of elements you just wrap it like using CTRL + G (like making a usual group). You can also use this extension to filter out unwanted SVG elements at all.
